&lt;!-- TWO STEPS TO INSTALL PERCENT CALCULATOR:

  1.  Copy the coding into the HEAD of your HTML document
  2.  Add the last code into the BODY of your HTML document  --&gt;

&lt;!-- STEP ONE: Paste this code into the HEAD of your HTML document  --&gt;

&lt;SCRIPT LANGUAGE="JavaScript"&gt;
&lt;!-- Original:  Tom Richardson Jr. (gooftroop@geocities.com) --&gt;

&lt;! &gt;
&lt;! &gt;

&lt;!-- Begin
function calc1(form) {
a = form.a.value/100;
b = a*form.b.value;
form.total1.value = b;
}
function calc2(form) {
a = form.c.value;
b = form.d.value;
c = a/b;
d = c*100;
form.total2.value = d;
}

//  End --&gt;
&lt;/script&gt;


&lt;!-- STEP TWO: Copy this code into the BODY of your HTML document  --&gt;

&lt;center&gt;
&lt;form name="form1"&gt;
&lt;table border=1 cellpadding=4 cellspacing=1&gt;
&lt;tr&gt;
&lt;td align=center&gt;What is 
&lt;input type="text" name="a" size=5&gt; 
% of &lt;input type="text" name="b" size=5&gt;?&lt;/td&gt;
&lt;td align=center&gt;Answer: &lt;input type="text" name="total1" 
size=5 maxlength=40&gt;&lt;/td&gt;
&lt;td align=center&gt;&lt;input type="button" value="Calculate" 
onClick="calc1(this.form)"&gt;&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td align=center colspan=3 align=center&gt;Or...&lt;/td&gt;
&lt;/tr&gt;
&lt;tr&gt;
&lt;td align=center&gt;&lt;input type="text" name="c" size=5&gt;
&nbsp;is what 
percent of &lt;input type="text" name="d" size=5&gt;?&lt;/td&gt;
&lt;td align=center&gt;Answer: &lt;input type="text" name="total2"
